Role of imaging in assessment and detection of complications after bariatric surgery

Abstract

Abstract Background Bariatric surgery is performed to control morbid obesity secondary to failed medical approaches. Practical knowledge of post-surgical anatomy allows accurate interpretation of imaging findings related to normal post-surgical anatomy and common post-surgical complications. The purpose of this study was to highlight the role of imaging in the assessment and detection of complications after bariatric surgery. Results This prospective study included 49 patients who had bariatric surgery. Sleeve gastrectomy was the most common bariatric surgery. The leak was the commonest complication (12%). The sensitivity of upper GI series for diagnosis of post-operative complication after bariatric surgery was 70% and specificity 94% while the sensitivity of CT study was 95% and specificity 95%. Conclusion CT has a golden role in the diagnosis of post-operative complications. Both post-contrast CT and upper GI series should be used in diagnosing complications following bariatric surgery. US is useful for diagnosis of a superficial problem.
